Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the unevenness amplification member and the unevenness detection method described in Patent Document 1, the unevenness amplification member is not attached to the user's finger. Therefore, when the user detects the uneven shape of the object to be inspected with the unevenness amplification member, the unevenness amplification member may slip off the user's finger.

[0005] When the surface to be inspected of the object to be inspected is the side surface or the ceiling surface of the object, etc., the user has to sandwich the unevenness amplification member between his / her own finger and the object to be inspected. As a result, the user has to align the unevenness amplification member and the finger using another finger on the same side as the hand using the unevenness amplification member or a finger of the hand on the opposite side of the hand using the unevenness amplification member. The user also has to constantly press the object to be inspected through the unevenness amplification member so that the unevenness amplification member does not fall off the finger even while observing the uneven shape of the surface to be inspected. Therefore, there is a problem that the burden on the user when using the unevenness amplification member is large and the user gets tired.

[0006] The present disclosure aims to provide a concavo-convex amplification tool capable of reducing the burden on a user when using a concavo-convex amplification member.

Means for Solving the Problems

[0007] The concavo-convex amplification tool for solving the above problems includes an amplification member that amplifies the sensitivity to the concavo-convex shape of an object with respect to the concavo-convex shape of a target that traces the concavo-convex shape of the surface of the object, a fixing member that arranges the amplification member with respect to the target while maintaining the deformation function of the amplification member for amplifying the sensitivity, and.

Effects of the Invention

[0008] According to the present disclosure, it is possible to provide a concavo-convex amplification tool capable of reducing the burden on a user when using a concavo-convex amplification member.

Modes for Carrying Out the Invention

[0010] Hereinafter, an embodiment of the present disclosure will be mainly described with reference to the accompanying drawings.

[0011] (First Embodiment) FIG. 1 is a schematic diagram showing the uneven amplification tool 1 according to the first embodiment of the present disclosure. FIG. 1 schematically shows an enlarged view of the tip side of the user's finger F that attempts to detect the uneven shape C of the surface S by tracing the surface S of the object OB to be inspected. In FIG. 1, a concave shape is shown as an example of the uneven shape C, but it is not limited thereto. The uneven shape C may be a convex shape. FIG. 2 is a schematic diagram showing a first example of the configuration on one side of the uneven amplification tool 1 in FIG. 1. FIGS. 1 and 2 schematically show a first example of the configuration of the uneven amplification tool 1.

[0012] The uneven amplification tool 1 is worn by a user who attempts to detect the uneven shape C of the surface S of the object OB. In the present disclosure, the "object OB" includes, for example, an object to be inspected when the user inspects the uneven state of the surface S using the uneven amplification tool 1. The object OB may include any object formed of metal, synthetic resin, rubber, etc. For example, the object OB includes painted products of automobiles, painted products of other transportation equipment, molds used in injection molding and press working, and other industrial products. The "surface S of the object OB" includes, for example, the painted surface of the object OB. The "uneven shape C" means, for example, the shape of a concave or convex portion with respect to the reference surface of the surface S of the object OB.

[0013] The unevenness amplification tool 1 is used for inspecting the swelling, bumps, and dents in the painting of painted products such as automobiles and transportation equipment, inspecting the unevenness of molds used in injection molding and press working, and inspecting the surface conditions of other industrial products. The unevenness amplification tool 1 may be used, for example, for detecting the surface strain of a steel plate and surface inspection during metal surface treatment. The unevenness amplification tool 1 may be used for detecting a fine uneven shape C in which the height dimension of the tip of a convex part or the bottom end of a concave part with respect to the reference surface of the surface S of the object OB is on the micron order. Without being limited to this, the unevenness amplification tool 1 may also be used for detecting an uneven shape C with a height of 1 mm or more.

[0014] The user, for example, attaches the unevenness amplification tool 1 to the index finger F of the hand, which is a part of his or her own body, and traces the surface S of the object OB with the index finger F. The user moves the index finger F of the hand and the amplification member 10 along the surface S of the object OB while arranging an amplification member 10, which will be described later, between the surface S of the object OB and the index finger F. When the amplification member 10 comes into contact with the uneven shape C of the surface S of the object OB, the amplification member 10 deforms. At this time, the user who touches the amplification member 10 by wearing the unevenness amplification tool 1 obtains an amplified tactile sensation compared to the tactile sensation of the uneven shape C obtained when directly tracing the surface S of the object OB.

[0015] The unevenness amplification tool 1 amplifies the user's tactile sensation with respect to the uneven shape C. The unevenness amplification tool 1 has an amplification member 10 that amplifies the sensitivity with respect to the uneven shape C to be traced of the uneven shape C of the surface S of the object OB. In the present disclosure, "object" includes, for example, a part of the user's body. "Part of the body" includes, for example, the finger F of the hand. "Sensitivity" means, for example, the degree of tactile sensation that the user obtains with respect to the uneven shape C.

[0016] The amplifying member 10 is configured to be elastically deformable when it moves over the surface S and approaches the uneven shape C by an operation of tracing the surface S of the object OB. The amplifying member 10 may include, for example, a metal coil spring as used in the prior art described in Patent Document 1. Examples of the metal used for the coil spring include, but are not limited to, hard steel wire, piano wire, stainless steel wire, silicon chromium steel oil tempered wire, and Mn-Cr steel hot forming spring material. In addition, the amplifying member 10 may be made of resin. Examples of the resin include, but are not limited to, polyethylene terephthalate (PET), polyacetal, polycarbonate, ABS (Acrylonitrile-Butadiene-Styrene) resin, polyester, nylon, polypropylene, polyvinyl chloride, and acrylic.

[0017] The unevenness amplifying tool 1 has a fixing member 20 that arranges the amplifying member 10 with respect to the object while maintaining the deformation function of the amplifying member 10 for amplifying the sensitivity to the uneven shape C of the object of tracing the uneven shape C. In the present disclosure, the "deformation function of the amplifying member 10" includes, for example, a function of changing the shape when the amplifying member 10 moves over the surface S and approaches the uneven shape C by an operation of tracing the surface S of the object OB. The fixing member 20 includes, for example, tape, adhesive, adhesive sheet, and glue.

[0018] The unevenness amplifying tool 1 has a mounting body 30 to which the amplifying member 10 is attached by the fixing member 20. The mounting body 30 is for mounting on the object. The mounting body 30 includes, for example, a finger sack, gloves, and work gloves. The gloves include, for example, plastic gloves, rubber gloves, sewn gloves, and knitted gloves. The mounting body 30 may be, for example, made of rubber and thin and elastic. In the example shown in FIG. 1, the mounting body 30 is mounted on the index finger F of the user's hand as the object.

[0019] The uneven amplification tool 1 has a first string 40 that is inserted into a through-hole 11 of an amplification member 10 and has both ends fixed by a fixing member 20. One end of the first string 40 is fixed by the fixing member 20 at a first fixing portion 41 and the other end is fixed by the fixing member 20 at a second fixing portion 42 on the surface of the wearing body 30. The first string 40 positions the amplification member 10 along the first string 40 between the first fixing portion 41 and the second fixing portion 42 with the first fixing portion 41 and the second fixing portion 42 fixed by the fixing member 20 on the surface of the wearing body 30. The first string 40 may or may not have elasticity so as to be stretchable and contractible.

[0020] The uneven amplification tool 1 has a protective sheet 50 disposed at a portion of the amplification member 10 facing the surface S of the object OB when the user wears the uneven amplification tool 1 and traces the surface S of the object OB. The protective sheet 50 is composed, for example, of tape, resin, non-woven fabric, woven fabric, rubber, and paper. However, when the protective sheet 50 is composed of rubber, it is preferable that a predetermined coating is applied to the rubber in order to reduce the friction with the surface S when the user wears the uneven amplification tool 1 and traces the surface S and make it slippery. In the present disclosure, "sheet" means formed, for example, in a film shape, a membrane shape, and a foil shape.

[0021] As shown in FIG. 1, the protective sheet 50 is disposed between the amplification member 10 and the surface S and moves in accordance with the movement of the index finger F of the hand and the amplification member 10. The protective sheet 50 protects the surface S so that the surface S is not damaged by contact with the amplification member 10 when the user wears the uneven amplification tool 1 and traces the surface S. The protective sheet 50 may be a thin and rigid sheet that is elastically deformable. The protective sheet 50 has flexibility and flexibility to the extent that it can be deformed along the uneven shape C of the surface S of the object OB.

[0022] As shown in FIGS. 1 and 2, the amplification member 10 of the uneven amplification tool 1 is arranged with respect to the object so as to be position-variable with respect to the object. For example, the amplification member 10 is arranged on the finger belly side of the index finger F of the user's hand as the object. At this time, the amplification member 10 is arranged so as to be position-variable with respect to the finger belly of the index finger F. The amplification member 10 is not fixed on the surface of the wearing body 30 and can move within a predetermined range on the surface of the wearing body 30 when not pressed against the surface S of the object OB.

[0023] The amplification member 10 is position-variable along the first string 40. For example, the amplification member 10 is movable along the first string 40 between both ends of the first string 40 fixed by the fixing member 20 on the surface of the wearing body 30. The amplification member 10 is restricted to move along the first string 40 by inserting the first string 40 through the through portion 11 of the amplification member 10. On the other hand, the amplification member 10 can move on the surface of the wearing body 30 along the first string 40 within the range between the first fixing portion 41 and the second fixing portion 42 of the first string 40 fixed by the fixing member 20.

[0024] FIG. 3 is a schematic diagram showing a second example of the configuration on one side of the uneven amplification tool 1 in FIG. 1. FIG. 3 schematically shows a second example of the configuration of the uneven amplification tool 1. In the first example shown in FIGS. 1 and 2, the uneven amplification tool 1 has been described as having the first string 40 inserted through the through portion 11 of the amplification member 10 and having both ends fixed by the fixing member 20, but it is not limited thereto.

[0025] In the second example shown in FIG. 3, the uneven amplification tool 1 may have a second string 60, one end of which is connected to each of both ends of the amplification member 10 and the other end of which is fixed by a fixing member 20, instead of the first string 40. The second string 60 includes one second string 60a connected to one end of the amplification member 10 and the other second string 60b connected to the other end of the amplification member 10. One end of the second string 60a is connected to one end of the amplification member 10 on the surface of the wearing body 30, and the other end is fixed by the fixing member 20 at the first fixing portion 61. One end of the second string 60b is connected to the other end of the amplification member 10 on the surface of the wearing body 30, and the other end is fixed by the fixing member 20 at the second fixing portion 62. The second string 60 positions the amplification member 10 so as to be sandwiched between the second string 60a and the second string 60b between the first fixing portion 61 and the second fixing portion 62. The second string 60 may have elasticity so as to be stretchable and contractible, or may not have elasticity.

[0026] Also in the second example shown in FIG. 3, the amplification member 10 of the uneven amplification tool 1 is arranged with respect to the object so as to be position-variable with respect to the object. For example, the amplification member 10 is arranged on the finger belly side of the index finger F of the user's hand as the object. At this time, the amplification member 10 is arranged so as to be position-variable with respect to the finger belly of the index finger F. The amplification member 10 is not fixed on the surface of the wearing body 30, and can move within a predetermined range on the surface of the wearing body 30 in a state where it is not pressed against the surface S of the object OB.

[0027] The amplification member 10 may be position-variable, for example, by the deflection or expansion and contraction of the second string 60. For example, the amplification member 10 may be movable in a state of being sandwiched between the second string 60a and the second string 60b fixed by the fixing member 20 on the surface of the wearing body 30. Since both ends of the amplification member 10 are respectively connected to the second string 60a and the second string 60b, the amplification member 10 is in a region sandwiched between the second string 60a and the second string 60b, and is restricted from moving within a region based on the deflection and expansion and contraction of each of the second string 60a and the second string 60b. On the other hand, the amplification member 10 can move on the surface of the wearing body 30 with respect to the second string 60 within the region sandwiched between the second string 60a and the second string 60b fixed by the fixing member 20.

[0028] FIG. 4 is a schematic diagram showing a third example of the configuration on one side of the uneven amplification tool 1 of FIG. 1. FIG. 4 schematically shows a third example of the configuration of the uneven amplification tool 1. In the first and second examples shown in FIGS. 1 to 3, the surface of the mounting body 30 of the uneven amplification tool 1 is continuously formed without cuts or the like, but is not limited to this.

[0029] In the third example shown in FIG. 4, the mounting body 30 of the uneven amplification tool 1 may have a cut 31 formed in the portion where the amplification member 10 is disposed. When the amplification member 10 is pressed against the surface S of the object OB when the user traces the surface S while wearing the uneven amplification tool 1, it comes into direct contact with the fingertip of the user's index finger F exposed from the cut 31. When the user presses the amplification member 10 against the surface S of the object OB when tracing the surface S while wearing the uneven amplification tool 1, the user directly feels the contact of the amplification member 10 with the fingertip of his or her index finger F through the cut 31 of the mounting body 30.

[0030] FIG. 5 is a schematic diagram showing a fourth example of the configuration on one side of the uneven amplification tool 1 of FIG. 1. FIG. 5 schematically shows a fourth example of the configuration of the uneven amplification tool 1. In the first to third examples shown in FIGS. 1 to 4, the uneven amplification tool 1 has been described as having only one amplification member 10, but is not limited to this.

[0031] In the fourth example shown in FIG. 5, the uneven amplification tool 1 may have a plurality of amplification members 10. The plurality of amplification members 10 may be attached to the same surface of the mounting body 30. For example, the plurality of amplification members 10 may be attached to the bottom surface of the mounting body 30 located on the fingertip side of the user's index finger F when the mounting body 30 is worn by the user. As an example, two amplification members 10 may be attached to the bottom surface of the mounting body 30 so as to be parallel to each other.

[0032] At this time, similar to the first example shown in FIG. 2, the first strings 40 and the protective sheets 50 are arranged for each of the two amplification members 10. Each of the two first strings 40 is fixed by the fixing member 20 at the first fixing portion 41 and the second fixing portion 42. Each of the two first strings 40 positions the amplification member 10 along the first string 40 between the first fixing portion 41 and the second fixing portion 42 in a state where the first fixing portion 41 and the second fixing portion 42 are fixed by the fixing member 20 on the bottom surface of the wearing body 30.

[0033] The plurality of amplification members 10 included in the uneven amplification tool 1 may have different magnification factors for amplifying the sensitivity to the target uneven shape C that traces the uneven shape C of the surface S of the object OB. In the present disclosure, the "magnification factor for amplifying the sensitivity" includes, for example, the amplification magnification of the sensitivity to the uneven shape C amplified by the amplification member 10 with respect to the sensitivity when the target traces the uneven shape C without using the uneven amplification tool 1 as a reference. The magnification factor for amplifying the sensitivity can be adjusted according to, for example, the spring characteristics including the shape, length, width, wire diameter, elastic modulus, and number of turns of the spring of the amplification member 10.

[0034] FIG. 6 is a schematic diagram showing a fifth example of the configuration of the uneven amplification tool 1 in FIG. 1. In the fourth example shown in FIG. 5, it was described that the uneven amplification tool 1 has a plurality of amplification members 10 on the same surface of the wearing body 30, but the present invention is not limited to this.

[0035] In the fifth example shown in FIG. 6, the plurality of amplification members 10 included in the uneven amplification tool 1 may be attached to different surfaces of the wearing body 30. For example, when the wearing body 30 is worn by a user, the plurality of amplification members 10 may be attached to at least two of the upper surface of the wearing body 30 located on the back side of the index finger F of the user, the bottom surface of the wearing body 30 located on the fingertip side of the index finger F of the user, and the side surface located between the upper surface and the bottom surface. As an example, three amplification members 10 may be attached to the upper surface, the bottom surface, and the side surface of the wearing body 30, respectively.

[0036] At this time, as in the first example shown in FIG. 2, the first string 40 and the protective sheet 50 are arranged for each of the three amplifying members 10. Each of the three first strings 40 is fixed by the fixing member 20 at the first fixing portion 41 and the second fixing portion 42. With the first fixing portion 41 and the second fixing portion 42 fixed by the fixing member 20, the amplifying member 10 is positioned along the first string 40 between the first fixing portion 41 and the second fixing portion 42 on the upper surface, the bottom surface, and the side surface of the wearing body 30, respectively.

[0037] The plurality of amplifying members 10 included in the unevenness amplifying tool 1 may have different magnification factors for amplifying the sensitivity to the target unevenness shape C that traces the unevenness shape C of the surface S of the object OB, as in the fourth example shown in FIG. 5. For example, the magnification factor for amplifying the sensitivity may be adjusted for each of the three amplifying members 10 arranged on the upper surface, the bottom surface, and the side surface of the wearing body 30 according to the sensitivity of the back, the pad, and the side surface of the user's index finger F. For example, when the tactile sensation of the pad of the user's index finger F is the most sensitive among the back, the pad, and the side surface of the index finger F, the magnification factor for amplifying the sensitivity of the amplifying member 10 arranged on the bottom surface of the wearing body 30 may be adjusted to be the lowest. On the other hand, when the tactile sensation of the back of the user's index finger F is the least sensitive among the back, the pad, and the side surface of the index finger F, the magnification factor for amplifying the sensitivity of the amplifying member 10 arranged on the upper surface of the wearing body 30 may be adjusted to be the highest.

[0038] According to the unevenness amplifying tool 1 according to the first embodiment as described above, it is possible to reduce the burden on the user when using the unevenness amplifying member, that is, the amplifying member 10. The unevenness amplifying tool 1 has, in addition to the amplifying member 10, a fixing member 20 that maintains the deformation function of the amplifying member 10 for amplifying the sensitivity to the target unevenness shape C and arranges the amplifying member 10 with respect to the target. Since the amplifying member 10 is stably arranged with respect to the target by the fixing member 20, the displacement of the amplifying member 10 with respect to the target when the target traces the unevenness shape C of the surface S of the object OB is reduced.

[0039] Even when the surface S, which is the surface to be inspected of the object OB serving as the subject, is the side surface, ceiling surface, etc. of the object OB, the user does not need to consciously sandwich the amplification member 10 between their finger F and the subject. For example, the user does not need to align the amplification member 10 and the finger F using another finger on the same side as the hand using the unevenness amplification tool 1 or a finger of the hand on the opposite side of the hand using the unevenness amplification tool 1. Even when the user is observing the uneven shape C of the surface to be inspected, the user does not need to hold the amplification member 10 using another finger on the same side as the hand using the unevenness amplification tool 1 or a finger of the hand on the opposite side of the hand using the unevenness amplification tool 1. Therefore, the burden on the user when using the amplification member 10 is small, and the fatigue of the user's body is reduced.

[0040] The amplification member 10 is arranged with respect to the object so as to be position-variable with respect to the object. Thereby, the amplification member 10 can easily maintain its own deformation function when detecting the uneven shape C without being strongly fixed to the object. Therefore, the effect of amplifying the sensitivity to the uneven shape C is maintained without the deformation function of the amplification member 10 being hindered. In addition, the user can also align the amplification member 10 at the position where the tactile sense is most sensitive for each object on which the amplification member 10 is arranged. The unevenness amplification tool 1 also enables fine adjustment of the position of the amplification member 10 with respect to the object for different users, and can be used by any user regardless of the user selected.

[0041] The uneven amplification tool 1 further has a first string 40 that is inserted into a through-hole 11 of the amplification member 10 and both ends of which are fixed by a fixing member 20. The amplification member 10 is position-variable along the first string 40. Thereby, the amplification member 10 can easily maintain its own deformation function when detecting the uneven shape C without being strongly fixed to the object. Therefore, the effect of amplifying the sensitivity to the uneven shape C is maintained without the deformation function of the amplification member 10 being hindered. In addition, the user can also align the amplification member 10 along the first string 40 at the position where the tactile sensation is most sensitive for each object on which the amplification member 10 is arranged. The uneven amplification tool 1 enables fine adjustment of the position of the amplification member 10 with respect to the object for each different user along the first string 40, and can be used by any user regardless of the user selected.

[0042] The uneven amplification tool 1 further has a second string 60 with one end connected to each of both ends of the amplification member 10 and the other end fixed by a fixing member 20. The amplification member 10 is position-variable due to the deflection of the second string 60. Thereby, the amplification member 10 can easily maintain its own deformation function when detecting the uneven shape C without being strongly fixed to the object. Therefore, the effect of amplifying the sensitivity to the uneven shape C is maintained without the deformation function of the amplification member 10 being hindered. In addition, the user can also align the amplification member 10 by the second string 60 at the position where the tactile sensation is most sensitive for each object on which the amplification member 10 is arranged. The uneven amplification tool 1 enables fine adjustment of the position of the amplification member 10 with respect to the object for each different user by the second string 60, and can be used by any user regardless of the user selected.

[0043] The unevenness amplification tool 1 is a mounting body 30 to which an amplification member 10 is attached by a fixing member 20, and has a mounting body 30 to be mounted on a target. Thereby, the mountability of the unevenness amplification tool 1 with respect to the target is improved. For example, the user can easily arrange the amplification member 10 by mounting the mounting body 30 on his or her own finger F. Since the amplification member 10 is stably arranged with respect to the target by the fixing member 20 in the mounting body 30, the displacement of the amplification member 10 with respect to the target when the target traces the uneven shape C of the surface S of the object OB is reduced.

[0044] Even when the surface S, which is the inspection surface of the object OB to be inspected, is the side surface and ceiling surface of the object OB, etc., the user does not need to consciously sandwich the amplification member 10 between his or her own finger F and the object to be inspected. For example, the user does not need to align the amplification member 10 with the finger F using another finger on the same side as the hand wearing the mounting body 30 of the unevenness amplification tool 1 or a finger of the hand on the opposite side of the hand wearing the mounting body 30. Even while the user is observing the uneven shape C of the inspection surface, the user does not need to hold the amplification member 10 using another finger on the same side as the hand wearing the mounting body 30 or a finger of the hand on the opposite side of the hand wearing the mounting body 30. Therefore, the burden on the user when using the amplification member 10 is small, and the fatigue of the user's body is reduced.

[0045] The mounting body 30 has a cut 31 formed in a portion where the amplification member 10 is arranged. Thereby, the unevenness amplification tool 1 can directly bring a part of the target on which the mounting body 30 is mounted into contact with the amplification member 10. When the user presses the amplification member 10 against the surface S of the object OB when tracing the surface S with the unevenness amplification tool 1 mounted, the user can also directly feel the contact of the amplification member 10 with the fingertip of his or her index finger F through the cut 31 of the mounting body 30. Therefore, the effect of amplifying the sensitivity to the uneven shape C by the amplification member 10 is improved. In addition, even if the mounting body 30 is a thick glove or work glove, etc., for example, the method of attaching the amplification member 10 to the target as shown in FIGS. 2 and 3 can be applied.

[0046] A plurality of amplification members 10 are attached to the same surface of the wearing body 30. As a result, the area where the amplification members 10 are arranged with respect to the object increases. Therefore, when the user wears the uneven amplification tool 1 and traces the surface S once, the detectable region of the uneven amplification tool 1 with respect to the uneven shape C of the surface S of the object OB increases. Therefore, when the user wears the uneven amplification tool 1 and traces the surface S of the object OB, the user can detect the uneven shape C in a wider range on the surface S with a single operation.

[0047] A plurality of amplification members 10 are attached to different surfaces of the wearing body 30. As a result, the uneven amplification tool 1 can arrange the amplification members 10 with respect to each of a plurality of different surfaces of the object. For example, when the user wears the uneven amplification tool 1 on his or her index finger F, it is also possible to arrange the amplification members 10 on the back, the belly, and the side surface of the index finger F. This improves the degree of freedom in the orientation of the object when tracing the surface S of the object OB. When the user tries to detect the uneven shape C by tracing the surface S of the object OB, the user can freely determine the direction in which his or her index finger F as the object faces the surface S without being limited to the belly side.

[0048] The plurality of amplification members 10 have different magnification factors for amplifying sensitivity. As a result, the uneven amplification tool 1 can arrange amplification members 10 with various magnification factors with respect to the object. When the user wears the uneven amplification tool 1 on his or her index finger F, for example, the uneven amplification tool 1 can also arrange amplification members 10 with different magnification factors with respect to the back, the belly, and the side surface of the index finger F, where the original tactile sensitivities are different when the uneven amplification tool 1 is not worn. For example, when the tactile sensation of the belly of the index finger F is the most sensitive among the back, the belly, and the side surface of the index finger F, the user can also arrange the amplification member 10 with the lowest magnification factor for amplifying sensitivity on the bottom surface of the wearing body 30. On the other hand, when the tactile sensation of the back of the index finger F is the least sensitive among the back, the belly, and the side surface of the index finger F, the user can also arrange the amplification member 10 with the highest magnification factor for amplifying sensitivity on the upper surface of the wearing body 30.

[0049] In the above-described first embodiment, the target was described as including, for example, a part of the user's body, but it is not limited thereto. The target may include a part of a machine such as a robot that attempts to detect the uneven shape C by inspecting the state of the surface S of the object OB. The "part of the machine" may include, for example, a detection module for inspecting the state of the surface S of the object OB and detecting the uneven shape C. The "detection module" may include, for example, a sensor such as a strain gauge. At this time, the "sensitivity" may mean, for example, the degree of output of the sensor signal obtained by the machine such as a robot with respect to the uneven shape C using the detection module.

[0050] In the above-described first embodiment, the unevenness amplification tool 1 was described as a mounting body 30 to which the amplification member 10 is attached by the fixing member 20 and having the mounting body 30 to be mounted on the target, but it is not limited thereto. The unevenness amplification tool 1 may not have the mounting body 30. For example, the unevenness amplification tool 1 may be configured such that the amplification member 10 is directly fixed to the target by the fixing member 20 without passing through the mounting body 30. For example, both ends of the amplification member 10 may be directly fixed by the fixing member 20 on the surface of the target. When the target includes a detection module of a machine such as a robot, the fixing member 20 may further include solder in addition to or in place of tape, adhesive, adhesive sheet, glue, and the like. The amplification member 10 may be directly fixed to the surface of the detection module with solder, for example.

[0051] In the above-described first embodiment, the fixing member 20 was described as including, for example, tape, adhesive, adhesive sheet, glue, etc., but is not limited thereto. The fixing member 20 may include, for example, the wearing body 30 itself. For example, the amplification member 10 may be arranged with respect to the object while maintaining the deformation function for amplifying the sensitivity by directly connecting the first string 40 or the second string 60 to a wearing body 30 including a finger sack, gloves, mittens, etc. For example, the amplification member 10 may be arranged with respect to the object while maintaining the deformation function for amplifying the sensitivity by passing the first string 40 or the second string 60 through a hole formed on the surface of a wearing body 30 including a finger sack, gloves, mittens, etc. At this time, a knot such as a bow knot, which is larger than the diameter of the hole formed on the surface of the wearing body 30, may be formed on the first string 40 or the second string 60.

[0052] In the above-described first embodiment, as shown in FIGS. 1 to 6, the amplification member 10 is vertically arranged along the extending direction of the user's finger F, but is not limited thereto. The amplification member 10 may be horizontally arranged so as to be orthogonal to the extending direction of the user's finger F.

[0053] In the above-described first embodiment, as shown in FIG. 5, it was described that a plurality of amplification members 10 are attached in parallel on the same surface of the wearing body 30, but is not limited thereto. The plurality of amplification members 10 may be attached to the same surface of the wearing body 30 based on any other arrangement relationship different from the parallel relationship. For example, the plurality of amplification members 10 may be attached to the same surface of the wearing body 30 obliquely to each other. At this time, the plurality of amplification members 10 may or may not cross each other. The uneven amplification tool 1 may have a plurality of amplification members 10 on each of different surfaces of the wearing body 30. At this time, the arrangement relationship of the plurality of amplification members 10 may be the same or different between different surfaces of the wearing body 30.

[0054] In the above-described first embodiment, it was described that the magnification factors for amplifying the sensitivity of the plurality of amplification members 10 are different from each other, but is not limited thereto. The magnification factors for amplifying the sensitivity of the plurality of amplification members 10 may be the same as each other.

[0055] (Second Embodiment) FIG. 7 is a schematic diagram showing a first example of the configuration on one side of the uneven amplification tool 1 according to the second embodiment of the present disclosure. FIG. 7 schematically shows a first example of the configuration of the uneven amplification tool 1.

[0056] In the first embodiment, it was described that the amplification member 10 is arranged with respect to the object so as to be position-variable with respect to the object, but it is not limited thereto. The amplification member 10 may be arranged with respect to the object so as to be position-fixed with respect to the object. Other configurations, functions, effects, modification examples, etc. are the same as those in the first embodiment, and the corresponding explanations also apply to the uneven amplification tool 1 according to the second embodiment. Hereinafter, the same reference numerals are given to the components having the same configuration as those in the first embodiment, and the description thereof is omitted. The points different from the first embodiment will be mainly described.

[0057] In the first example shown in FIG. 7, the amplification member 10 may be covered by the fixing member 20. For example, the amplification member 10 may not be indirectly attached to the wearing body 30 by the first string 40 or the second string 60, but may be directly fixed to the surface of the wearing body 30 by the fixing member 20. Even in such a case, the amplification member 10 is arranged with respect to the object while maintaining the deformation function for amplifying the sensitivity. The amplification member 10 is not strongly fixed by the fixing member 20, but is elastically deformable to some extent when moving on the surface S by the operation of the object following the uneven shape C of the surface S of the object OB, and the position on the surface of the wearing body 30 is fixed.

[0058] According to the first example of the second embodiment as described above, the amplification member 10 is arranged more stably with respect to the object by the fixing member 20. As a result, the positional deviation of the amplification member 10 with respect to the object when the object follows the uneven shape C of the surface S of the object OB is further reduced. Therefore, similar to the first embodiment, the uneven amplification tool 1 can further reduce the burden on the user when using the amplification member 10.

[0059] FIG. 8 is a schematic diagram showing a second example of the configuration on one side of the uneven amplification tool 1 according to the second embodiment of the present disclosure. FIG. 8 schematically shows a second example of the configuration of the uneven amplification tool 1. In the first example shown in FIG. 7, the amplification member 10 is covered by the fixing member 20, but it is not limited thereto.

[0060] In the second example shown in FIG. 8, both ends of the amplification member 10 may be fixed by the fixing member 20. For example, the amplification member 10 may not be indirectly attached to the wearing body 30 by the first string 40 or the second string 60, but may be directly fixed to the surface of the wearing body 30 by the fixing member 20. Even in such a case, the amplification member 10 is arranged with respect to the object while maintaining the deformation function for amplifying the sensitivity. The amplification member 10 is not strongly fixed by the fixing member 20, but is elastically deformable when moving on the surface S and approaching the uneven shape C by the operation of the object following the surface S of the object OB. The position on the surface of the wearing body 30 is fixed.

[0061] According to the second example of the second embodiment as described above, the amplification member 10 is arranged more stably with respect to the object by the fixing member 20. As a result, the displacement of the amplification member 10 with respect to the object when the object follows the uneven shape C of the surface S of the object OB is further reduced. Therefore, similar to the first embodiment, the uneven amplification tool 1 can further reduce the burden on the user when using the amplification member 10.
